Sounds like a newer truck? No TPS? I run Mobil 1 as wellGetting a new tire to replace one I let get low and didn't know it. (so it wore) Also getting a front end alignment and everything getting balanced.
So.... While it's on the rack and the second only oil change after the Royal Purple break in oil, putting in some factory weight spec MOBIL 1
and a WIX filter.
I BELIEVE IN MOBIL 1 and synthetic oil in general. It don't "wear out" so as long as you keep it strained (new filters) and keep water out it will last. Internal combustion engines don't get hot enough to degrade synthetics.
I used to put it in the crank case and drive shaft of two racing motorcycles. Heck, I even put it in my lawn mowers.
